Additional quotes by Walter Isaacson

Leonardo’s relentless curiosity and experimentation should remind us of the importance of instilling, in both ourselves and our children, not just received knowledge but a willingness to question it — to be imaginative and, like talented misfits and rebels in any era, to think different.

Walter Issacson biographer of Steve Jobs:

I remember sitting in his backyard in his garden, one day, and he started talking about God. He [Jobs] said, “ Sometimes I believe in God, sometimes I don’t. I think it’s 50/50, maybe. But ever since I’ve had cancer, I’ve been thinking about it more, and I find myself believing a bit more, maybe it’s because I want to believe in an afterlife, that when you die, it doesn’t just all disappear. The wisdom you’ve accumulated, somehow it lives on.”

Then he paused for a second and said, “Yea, but sometimes, I think it’s just like an On-Off switch. Click. And you’re gone.” And then he paused again and said, “ And that’s why I don’t like putting On-Off switches on Apple devices.”
